gl'o all 'whom it 'may concern:

Be it known that I, DANIEn L. HOLDEN,

. of the city and county of Philadelphia, and

forming part of this specificatiomin whch- Figure 1 is a transversesection with one of `the receptacles for the non-congealable fluidbroken out. Fig. 2 `is a side vien', lwith one end in verticallongitudinal section. Fig. 3 is a plan view. Fig. 4 is an artificialblock of ice having a hand-hold frozen therein.

This invention relates to an improvement upon that feature of anice-machine known 'is the congealer or apparatus in which the congelation of the Water is effected. It relates more par icularly to thatform of conge'aler in which receptacles containing a cold noncongealableliquid are immersed in a tank of pure' water, sc as 'to freeze upon theoutside of said receptacles blocks of ice without incorporating theimpurities of the water.

Theinvention consists, first, in pivoting the receptacles for thenon-congealable liquid at the bottom, end connecting them by flexiblepipes with the main inlet and disch arge pipes, so that the saidreceptacles may be slightly rocked to one side upon their bottom pivots,to permit the easy removal of the unbroken block of ice formed betweenany two such 'receptacles.

The invention also consists in the method of subdivding such largeblocks of ice, which consists in freezing at metal blades in the saidblock ,and afterward strikin g a blow upon the blade tovdivide the blockat the desired point.

Thein'vention also further consists iufreezingaloopedcord into theblocks of ice, which .constitutes a permanent handheld for handling thesaid blocks. i

In the' drawing, A represents the tank, insulated with a poor conductorof heat, and provided -With an inlet, a, and an outlet, b, which i inletis employed-'for introducing fresh water into the. tank, and whichoutlet serves to drain -thefuncon gealed'porticns of water in thebottom` of ther-tank containing the sediment.'

Transvcrscly' wit-hin this tank are ,frrauged metallic receptacles B forthe non-congealablcv fluid.l These receptacles have baule-plates c, tocause thecold iiuid to thoroughly traverse the same in passing throughthe lengt-h of the said receptacles from one side of the tank to theother. 'The bottoms d of these receptacles are made of wood or some poorconductor of heat, to pre 'ent the `Water uponthe outside frornvfreezing to the bottom, and said bottoms are pivoted at their ends toangle-irons e, so as to allow the receptacles to have a slightoscllatory or rocking movement, for the purpose hereinafter described.

Upon one side of the tank, and dipping into thc bottoms of each of thecold-fluid receptacles, are pendent pipes f, which emerge through theside of the tank, and connect, through separate cocks g,with;acontinuous inlet-pipe, lz, runnin-g the Whole length of the tank, andhaving communication with the outlet-pipe from the refrigerator of `anice-machine, (not showu,) by which the non-congeala ble fluid isrefrigerated. Upon the opposite side of the tank, and into each of thereceptacles B, are arranged pipes i, which open through separate cocksinto a dischargepipe, j, extending the whole length of the tank, andcommunicating with the inlet-pipe of the refrigerator of .theice-machine,'so that the noncongealable `uid, which is charged with theheat extracted from the Water4 to be frozen,

continuous inlet-pipe g and the connection of Y with the continuousdischarge-pipe;

pipe i are made flexible, so as to allowthe receptacles to be rockedupon their bottom pivots, as be-- fore stated, and for said connectionssections of' rubber hose are employed.

Now, as the circulation of the non-congeala ble fluid is kept up by thepumps `of the 1ce `machine, the cold fluid, which is' below the'freezing-point, enters each of the receptacles through the pipes f,and,.passin g up and down around the baiile-plates .in close contact themetal Walls, emerges through the pipes i upon the other side. f Now, thetank. A being filled withpure AWater, which surrounds the saidreceptacles, the eiiect of the cold traversing currents is to freezeupon the outside of 'Fran i with - aereas f i taeles, and the ends ofthe receptacles which are packed .and the bottoms which are made of wooddo not freeze the water in contact therewith, and as there is always alayer of water near the bottom which is not frozen, and agraduallydiminishin g wall of water between each two receptacles, theimpurities in the water are thrown downv into this uneongealed body ofwater at the bottom. Now', when the freezing is complete, kthe watercontaining the sedimentand impurtiesis drawn o` at b. This, it will beseen, makes the freezing process a refining one, and the product ispure, clean', and purged of all color' and sediment. y

In freezing the large blocks of ice between. the receptacles B, which myinvention con-z templates, some means of removing and subdividing theblocks must be provided. In freezing, therefore, I suspend midwaybetween the receptacles several metal blades, l', Fig. 2, having eyesory hand-holds inthe top there of. Now, when-.the freezing is complete,the non-congealable fluid is sli ghtlywarmcdto loos-v en theblo'eks ofice from the receptacles, and therst half-block of ice, l, is lifted outby the eye of its `blade through the irst removable door, X,'at the top.New, when the' next fullsized block, l', is to beremoved, the merit ofarranging the receptacles to rock will be apparent, for' the firstreceptacle will not allow the' block to be removed until it is rocked toone side..-l flhisbeing permitted, however, by

its pivots at the bottom and lits ilexible hose, thel block isreadilyliftedout through the second door by its lifting-blades l', andso on.

`In order to vsubdivide these large `blocks equally and without'loss,these blades are made lint, and extend well down into the block,

with the eye or head ofthe blade swelled to a" greater thickness.Now,.after the'block is which evenly divides the block in transversedirection without loss from fragments, and frees the blades for uselagain. In freezing these blades in the blocks of ice the blades, it willbe seen, have a double function. v I'may, however, as a modification,freeze into blocks of ice of any. size aloop of lcord to form ahand-hold, as in Fig. 4, which'is tolle permanently and rigidlyincorporated in the block as a new article of manufacture, whichhandheld will greatly facilitate the handling of the ice on the part ofboth dealer and consumer.

I am aware that vbars of metal have been frozen into blocks of ice toconstitute a hold to handle them by; but they were not embedded in' anddesigned to go with the smaller blocks-of ice for retail purposes, butwere only employed forhandlin g the larger blocks, which werealterwardsubdivided and the metal bars .f- These, itwill 'be seen, didiiotnconfv removed. stitute acomplete article of manufacture; and

.metal bars, moreover, would not be applicable for use as hand-holds inretailing, as theyiare liable to rust, are too expensive, and theireonductivit-y would allow them to -sooiunelt out..- I therefore confinethis feature of my invention g to a block 4of ice provided with aflexible cord.
